Why LiteSIP Roofs

The same modular performance behind every Modular Brands build

The same composite structural insulated panels (C‑SIPs) used in our full home kits, sized and engineered for accessory dwelling units.

Stronger, Lighter, Smarter

Ultra-lightweight panels with exceptional structural integrity — faster, safer installation than conventional truss-and-deck roofing.

Energy Efficient

High-performance insulation keeps buildings naturally cooler in summer and warmer in winter, cutting energy costs year-round.

Durable by Design

Resistant to fire, moisture, mold, and pests — a long-lasting, low-maintenance roofing system built to withstand the elements.

Fast & Flexible Install

Prefabricated panels allow for quick assembly and precise fits, eliminating many of the delays of traditional roofing.
